WATER-FILTER.

SPECIFICATION forming part of Letters Patent No. 406,126, dated July 2,1889.

` Application tiled January 19, 1889. Serial No. 296,863. (No model.)

T all whom it may con-cern;

Be it. known that I, JOHN J. CURRAN, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Tater-Filters; andl dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.'

My invent-ion relates to improvements in water-filters of the classwhich employ vitrified porous material for filtering, constructed in theform of a hollow shaft having a circular or a polygonal cross-section;and the objects of my improvements are, first, to provide a mechanismwhich shall be adapted to support such a filter within a pendent case,said case being adapted to be opened at its upper extremity forcleansing and repairing purposes, and the said pendent case being'supported within another case, the first of said cases being thereceiving-receptacle for the water to be filtered and the second of saidcases being the storage-reservoir for said water after it shall havebeen filtered; second, to provide between the said porous filter and itsretaining pendent case an open water-space connecting with perforationsthrough the sides of the said case for the better delivery of thefiltered water into the storage-reservoir; third, to construct thesidesof the said receivingreceptacle in aflaring form, the better and moreeconomically to connect it with and support it from the interior of theupper extremity of the said storage-reservoir; fourth, to removably andadj u'stably connect the said pendent receiving-receptacle withacleansin g and refuse-removing pipe located at or near the lowerextremity of said pendent receiving-receptacle; fifth, to adapt the saidconstructed mechanism to be used as a pressure-filter, so called, first,by providing suitable means for closing its upper extremity or the upperextremity of the said pendent receptacle and the said storage-reservoiragainst water-leakage under hydraulic pressure; second,by providing theinterior of the said porous filter with a rotary wiping-arm adapted tobe operated from the exterior of the said storage-reservoir; third, bysurrounding, in close proximity thereto, the said porous fil- .withinthe said reservoir.

structed as a pressure-filter', and having the t storage reservoirconstructed with double walls for the purpose of more effectuallyexcluding exterior heat from the stored water This view is taken on lineA, Fig. 4. Fig. 4 is a horizontal crosssection of the apparatus shown inFig. 3, taken on line B, Fig. 3. on line C, Fig. l, of thescrew-connection of thev receiving-receptacle with its refuse-removingpipe. Fig. 6 is a vertical section of a modified form of thescrew-connection shown in Fig. 5. Fig. 7 is a vertical section of theprotecting-jacket shown at S in Fig. 3.

Similar letters refer to similar parts throughout the several views.

Referring to the drawings, E is a porous lilter, preferably madeA in theform of a hollow cylinder, as shown; but it is obvious that any ,hollowshaft having a polygonal forni of crosssectiOn-may be used for thispurpose.

At F is a case which is preferably constructed with a flaring upperextremity, though it is obvious that the said iiaring sides might extendthe entire vertical length of the case without changing ythe nature ofmy invention. This case constitutes a water-receiver and carries theporous filter' E, between which and the said receiver F isan open spaceG, the top and bottom extremity of which space is closed by means oflayers of cement H, or of other suitable material, such as paraffine,wax, die. A

At I in Figs. l and 2, the receiver F is removably attached to thereservoir-case J in any suitable manner, but preferably by means of aflange attached to the top of the said receiver F, and extending overthe top of the said reservoir-case, as shown in said figures.

Fig. 5 is a vertical sectionv IOO A removable cover K is adapted toclose the open top of the receiving-case F, as shown in Figs. l and 2.In the pressure-filter, however, the cover K is secured to the parts Fand J in such a manner as to form an airtight and a water-tightconnection between the said parts. The receiver F is perforated at L toform passage-ways for the filtered water to enter the reservoir M, whereit is stored, and where it is drawn from through the faucet N.

O is a pipe connecting the lower extremity of the receiver F with theopen atmosphere through the outlet P. This outlet-pipe P is secured tothe reservoir J and to the connecting screw-coupling Q. Thisscrew-coupling Q is illustrated in an enlarged forni at Q in Fig. 5. Thepart R, having a nut therein, which is adapted to iit the part Q, may bea separate piece of metal, as shown in said Fig. 5, or-it may be formedas an integral part of the receiver F, as shown in Figs. I and 2. Theobject of the screw Q and nut R is to sccure the parts F and Jdetachably together, and to remove or to replace the said receiver Ffrom the case J it is obvious that it is only necessary to give the saidreceiver a few turns in the proper direction.v

In Fin'. 3, at S, is shown a perforated jacket, which may be made of anysuitable material, .preferably of metal. This jacket closely fitstheporous filter on its outer surface, and is adapted to protectitagainst t-he action of the water-pressure from within the said porousfilter, and the water may freely pass thro ugh the perforations in saidjacket from the said porous filter to the space G.

At T is a shaft journaled in a packing-box at U, and resting upon abridge-stop at V. To this shaft, at YV, `are att-ached radial armsconnecting with awiping-bar X, which bar X, by virtue of its. extendingthe entire vertical height of the said porous filter and contacting withthe inner surface thereof, is adapted, by means of the wheel Y, to beturned about the axis ot' the said shaft and remove accumulations ot'matter from the inner surface of said filter E, which, by opening theoutlet P, may be readily removed.

The operation ot' this water-filter is as follows: Water is introd uccdinto the receiver F, preferably by removing the cover or through thecover K, and, passing downward through the porous filter E, the space G,and the perforations L, iows into the storage-reservoir IWL where it isdrawn off through the outlet N.

I. In a water-filter, an inner receptacle having perforations near itslower extremity and carrying within its walls an outwardly-dischargingporous filter, in combination with an outer case, the said outer caseand the said inner receptacle being removably connected at their upper'extremities and the said` inner receptacle being adapted to be screwedinto position by means of a central screw and nut at itslower extremityand connecting with the said outer case, substantially as shown anddescribed.

2. In a water-filter, an inner water-receptacle having perforations nearits lower extremity and carrying within its walls anoutwardlydischarging porous lilter, between which and the saidwater-receptacle is an open space sealed above and below against `thepassage of water, except in a filtered state, in combination with anouter storage-reservoir, substantially as shown and described.

The inner water-receptacle F, having peri'orations near its lower end,the porous filter E and the erforated acket surrounding and a P e JOHNJ. CURRAN. Vtlitnesses:
